Question

users_controller.rb

class ProfilesController < ApplicationController
  before_filter :authenticate_user!

  def show
    @user = User.find(params[:id]) || User.find(current_user.id)
    @questions_for_about = @user.questions.for_about.order('id asc')
    @questions_for_personality = @user.questions.for_personality.order('id asc')
  end
end

用户＃show.html.erb

   <div class="element">
          Ethinicity:
          <%= @user.ethnicity.present? ? @user.ethnicity.name : "" %>
        </div>
        <div class="element">
          Education:
          <span class="select_for_education">
           <%= @user.education.present? ? @user.education.name : "" %>
        </div>

user.education.name只显示以下内容 - 教育：

使用以下选项不显示用户在其个人资料中选择的教育：

  <div class="element">
          Ethinicity:
          <%= best_in_place current_user, :ethnicity_id, :type => :select, collection: Ethnicity.all.map{|e| [e.id, e.name]}, :inner_class => 'education-edit', nil: 'Select Ethnicity' %>
        </div>
        <div class="element">
          Education:
          <span class="select_for_education">
        <%= best_in_place current_user, :education_id, :type => :select, collection: Education.all.map{|e| [e.id, e.name]}, :inner_class => 'education-edit', nil: 'Select Education' %>
        </div>

我做错了什么？如何让用户在他/她自己的个人资料中显示的教育显示在节目页面中？

先谢谢！

ethnicity.rb

class Ethinicity < ActiveRecord::Base
  attr_accessible :name
  has_many :users
end

education.rb

class Education < ActiveRecord::Base
  attr_accessible :name
  has_many :users
end

Answer 1

您遗失了belongs_to和has_many关系的has_one关联。需要在其表具有外键的模型中定义belongs_to关联定义。

鉴于你的模型，虽然可以想象其他方式，但我认为这些关联应该是这样的：

# User Model
class User < ActiveRecord::Base
  ...
  belongs_to  :ethnicity
  belongs_to  :education
end

# Ethnicity Model
class Ethinicity < ActiveRecord::Base
  attr_accessible :name
  has_many :users
end

# Education Model
class Education < ActiveRecord::Base
  attr_accessible :name
  has_many :users
end

未在用户显示的属性#show page
